Definitions

  • the present invention relates to an exhaust gas return system for an internal-combustion machine, in particular a diesel engine, for returning exhaust gas produced in the internal-combustion machine to fresh air to be supplied to the internal-combustion machine. Further, the invention relates to a method of returning exhaust gas, wherein the exhaust gas of the internal-combustion machine can be returned to the fresh air used for the internal-combustion machine.
  • the exhaust gas return system comprises a low-pressure supply line extending from an inlet to a compressor.
  • a high-pressure supply line extends from the compressor to the internal-combustion machine for supplying fresh air aspirated at the inlet to the internal-combustion machine, in particular a combustion engine.
  • the exhaust gas produced in the internal-combustion machine is fed via a high-pressure exhaust gas line from the internal-combustion machine to a turbine. From the turbine, the exhaust gas is fed via a low-pressure exhaust gas line to an outlet.
  • a low-pressure return line connected with the low-pressure exhaust gas line and the low-pressure supply line is provided, said low-pressure return line supplying part of the exhaust gas to the low-pressure supply line, whereby part of the exhaust gas is returned.
  • Such an exhaust gas return system has a drawback in that in particular during the cold start phase of the internal-combustion machine, the temperature of the fresh air to be supplied to the internal-combustion machine is not optimally adjusted and reaches the value required for satisfactory combustion only after some time. This results in unfavorable combustion in the internal-combustion machine such that, in particular in a diesel engine, the exhaust gas contains large portions of soot particles and entrained oil.
  • the soot particles and entrained oil contained in the exhaust gas are returned to the internal-combustion machine such that unwanted contaminants are concentrated in the internal-combustion machine, whereby the combustion process in the internal-combustion machine is deteriorated. Further, this leads to higher wear of the internal-combustion machine, in particular in the area of the inlet valves, and to fouling of swirl flaps.
  • the soot particles are critical for the cylinder bores of the internal-combustion machine.
  • an exhaust gas return system for an internal-combustion machine in particular a diesel engine, comprises a low-pressure supply line extending from an inlet to a compressor. From the compressor a high-pressure supply line extends to the internal-combustion machine. From the internal-combustion machine a high-pressure exhaust gas line leads to a turbine such that the exhaust gas produced in the internal-combustion machine can be supplied to the turbine. From the turbine a low-pressure exhaust gas line leads to an outlet. The low-pressure exhaust gas line and the low-pressure supply line have connected therewith a low-pressure return line for returning exhaust gas.
  • the high-pressure exhaust gas line has connected therewith a bypass line for utilizing the heat of the exhaust gas produced in the internal-combustion machine for heating the exhaust gas to be returned of the low-pressure return line.
  • the bypass line comprises a heat exchanger for heating at least part of the exhaust gas to be returned of the low-pressure return line. From the heat exchanger the bypass line extends back to the high-pressure exhaust gas line and/or past the turbine to the low-pressure exhaust gas line.
  • the bypass line extends in particular directly from the high-pressure exhaust gas line to the low-pressure exhaust gas line, i.e. past the turbine.
  • a heat exchanger is not required since the heat of the hot exhaust gas from the internal-combustion machine can be directly used for heating the exhaust gas to be returned.
  • the turbine is thus bypassed and is not allowed to extract heat from the exhaust gas.
  • the bypass line it is possible, due to return of the exhaust gas, to use the heat of the hot exhaust gas for heating the exhaust gas to be returned and/or for heating the fresh air to be supplied, without the contaminants contained in the exhaust gas being returned to the internal-combustion machine.
  • a high-pressure return line which may be necessary otherwise, can be omitted.
  • the heat of the exhaust gas is preferably used for heating the exhaust gas to be returned and only then for heating the turbine which, in particular together with the compressor, constitutes a turbo-charger. A delay in the heating of the exhaust gas to be returned caused by the heat capacity of the turbocharger is thus prevented. Further, higher temperatures are more rapidly reached in the low-pressure exhaust gas line such that any existing catalyst more rapidly operates in the optimal range.
  • an exhaust gas treatment device which may be provided in the low-pressure exhaust gas line, e.g. a catalyst, is heated before heating the turbocharger, whereby the emission of harmful exhaust gases and substances, such as No x , CO, SO 2 , is reduced. Since the rapid heating of the fresh air promotes as complete a combustion in the internal-combustion machine as possible, emission of harmful exhaust gases and substances is further reduced.
  • the bypass line and/or the high-pressure exhaust gas line comprise a bypass valve for adjusting the volume flow into the bypass line.
  • a bypass valve for adjusting the volume flow into the bypass line.
  • the bypass line comprises a turbine bypass valve which is adapted to determine the volume flow to be supplied past the turbine to the low-pressure exhaust gas line.
  • the turbine bypass valve is configured to determine the volume flow to be supplied via the bypass line to the turbine.
  • the low-pressure exhaust gas line and/or the low-pressure return line comprise an exhaust gas return valve.
  • the exhaust gas return valve is configured for adjusting the volume flow into the low-pressure return line.
  • the low-pressure return line may comprise a heat exchanger valve for adjusting the volume flow through the heat exchanger.
  • the low-pressure return line may comprise a bypass line via which the volume flow, which is not to be supplied to the heat exchanger, is directed past the heat exchanger.
  • exhaust gas produced in an internal-combustion machine is returned to a fresh air flow used for the internal-combustion machine.
  • first fresh air for the internal-combustion machine is aspirated.
  • a combustion process is performed in the internal-combustion machine.
  • the exhaust gas produced in the internal-combustion machine is fed towards an energy consumer, in particular a turbine.
  • At least part of the exhaust gas produced in the internal-combustion machine is returned to the aspirated fresh air.
  • at least part of the exhaust gas from the internal-combustion machine is used as heating gas for heating the exhaust gas to be returned.
  • the used heating gas may be entirely or partly fed to the energy consumer.
  • the method of returning exhaust gas according to the invention is further developed as described with reference to the exhaust gas return systems according to the invention.
  • the heating gas is supplied to the exhaust gas immediately in front of and/or immediately behind the energy consumer.
  • the amount of heating gas and/or the amount of returned exhaust gas is adjusted preferably in dependence on the temperature, in particular that of the fresh air supplied to the internal-combustion machine.
  • the exhaust gas from the internal-combustion machine is, to its full amount, supplied to the energy consumer, i.e. the exhaust gas is not used as heating gas for heating the exhaust gas to be returned. It is thus automatically recognized whether, for example, the cold start phase of the internal-combustion machine necessitates utilization of the exhaust gas from the internal-combustion machine as heating gas. Since utilization of the exhaust gas as heating gas is no longer necessary when the predetermined temperature has been reached, the exhaust gas is fully utilized by the energy consumer.
  • the exhaust gas return system according to the invention for an internal-combustion machine 10 comprises a low-pressure supply line 12 which feeds fresh air in the direction indicated by an arrow 16 from an inlet 14 to a compressor 18 .

  • the low-pressure exhaust gas line 26 and the low-pressure supply line 12 have connected therewith a low-pressure return line 32 .
  • the high-pressure exhaust gas line 22 has connected therewith a bypass line 34 which feeds at least part of the exhaust gas produced in the internal-combustion machine 10 in the direction indicated by an arrow 36 .
  • the volume flow fed in the direction indicated by an arrow 36 can be adjusted by means of a bypass valve 38 .
  • the exhaust gas fed in the direction indicated by arrow 36 is supplied via the bypass line 34 to a heat exchanger 40 by means of which the returned exhaust gas in the low-pressure return line 32 can be heated.
  • the bypass line 34 further comprises a turbine bypass valve 42 by means of which the volume flow into the bypass line 34 can be split up.
  • the turbine bypass valve 42 allows part of the heating gas of the bypass line 34 to be supplied in the direction indicated by an arrow 44 past the turbine 24 to the low-pressure exhaust gas line 26 . Further, part of the heating gas can be supplied via the turbine bypass valve 42 in the direction indicated by an arrow 46 to the turbine 24 .
  • the low-pressure exhaust gas line 26 further comprises a filter element 54 which is, for example, a diesel particulate filter. Further, the low-pressure exhaust gas line 26 includes an exhaust gas treatment device 56 which is in particular a catalyst.
  • the volume flow of the exhaust gas returned via the low-pressure return line 32 is adjustable by means of an exhaust gas return valve 58 arranged in the low-pressure exhaust gas line 26 and/or the low-pressure return line 32 .
  • the volume flow of the returned exhaust gas of the low-pressure return line 32 can be split up, by a heat exchanger valve 60 , into a volume flow supplied in the direction indicated by an arrow 62 to the heat exchanger 40 , and/or into a volume flow directed in the direction indicated by an arrow 64 via a bypass line 66 and past the heat exchanger 40 .
